Abstract

The purpose of this study is to simulate the process of autoignition at the end gas region in dual-fuel gas engine under PREMIER combustion conditions using elementary chemical reactions of diesel fuel and homogeneous natural gas-air mixture. Elementary reaction scheme of diesel fuel and natural gas in dual-fuel gas engine was developed to simulate the diesel fuel ignition and the auto-ignition inside end-gas during flame propagation of natural gas-air mixture. Simulation procedure of dual fuel gas engine with diesel fuel ignition and the auto-ignition inside end-gas compressed by the flame propagation was considered and checked in the simulated constant volume vessel. The auto-ignition inside end-gas region in dual-fuel gas engine can be occurred using proposed procedure of 3D CFD.
